ELITE AIP SUBMARINE 677 LADA

Elite air-independent-propulsion submarine built around stealth, submarine detection and direct surface/submarine combat. Across three research levels the 677 Lada gains survivability and combat power while retaining a fixed attack range, with the final MK3 adding cruise-missile launch capability.

[ TACTICAL READ ]
Coastal Stealth Hunter
Naval Combat
Surface-ship attack rises from 9 to 19 while submarine attack rises from 7 to 15 across the three research levels.
Coastal Trade-Off
Coastal waters apply -50% ATK and -50% DEF while also reducing speed and effective HP compared with the open-sea profile.
Late Capability
Research L3 / 677 Lada MK3 adds the confirmed cruise-missile system with capacity 1 and a 12-hour reload.
Shared Doctrine Research Timing
Eastern, Western and European doctrines use the same supplied schedule: L1 Day 2, L2 Day 13 and L3 Day 23. No doctrine-specific selector is required.

Economy Rule // Preserve Source Ordering
Cost and upkeep sequences are kept exactly in their supplied left-to-right order. No resource-icon names are inferred.

Other Defense // Neutral Preservation
The source explicitly identifies Surface Ship and Submarine attack and defense values. Additional defense values are shown at L2 and L3 without a safe textual target-class mapping, so they remain preserved as Other DEF Shown rather than being assigned invented meanings.

Coastal Combat
Coastal waters apply -50% ATK and -50% DEF at every supplied level.
Coastal Speed
1.5 at L1–L2 and 1.75 at L3.
Open-Sea Speed
2.25 at L1–L2 and 2.63 at L3.
Sight
Sight remains 50 across the complete supplied progression.
[ CONFIRMED SPECIAL MECHANICS ]

Stealth, Detection & Missile Launch

Stealth Unit
When the submarine is not in combat, it is not visible.
Stealth Detection
The Lada can reveal stealth submarines within its sight range.
Cruise Missile // MK3
At 677 Lada MK3, the source confirms capacity 1 with a 12-hour reload.
Missile Separation
Cruise-missile capacity/reload is a separate launcher mechanic and is not added to the direct surface/submarine combat values.
Data Separation // Direct Combat ≠ Sea State ≠ Missile System
Surface Ship and Submarine ATK/DEF are stored direct-combat values. Coastal ATK/DEF penalties, coastal speed and coastal HP form a separate environmental layer. Open-sea HP and speed remain separate from coastal values. Stealth and reveal-stealth are detection mechanics. Cruise-missile capacity and reload are a separate final-stage launch system.
